Internet radio streaming server
One fast streaming server for every station you host. Compatible with the Icecast and SHOUTcast tools you already use.
Open source core under AGPL-3.0. A commercial Hosting edition for radio hosting companies. Written in Crystal, made in Sweden.
01Who it's for
Run hundreds of customer stations in one process. Create, suspend and delete them through an API or straight from WHMCS, enforce each plan's limits, and export the usage and royalty data your billing and reporting need.
See the Hosting editionRun your own station on your own server with the open source core. Keep your encoder, keep your players, drop in a single binary or a Docker container. Free under the AGPL-3.0.

Lurcast speaks the Icecast and SHOUTcast protocols, so switching servers does not mean reconfiguring every DJ's encoder or every listener's app.
Compatible with the protocols, not affiliated with either project. See the notice in the footer.
03Performance
Measured on our own load test: 5,000 concurrent listeners, every one served at full rate, with no dropped connections.
Figures from a single load test run by us. Your numbers will depend on hardware, bitrate and network.
04Hosting edition
A commercial license on top of the open source core, built for companies that run many customer stations at once.
Create, update, suspend and delete stations through an API, without restarting the server. Hundreds of stations run in a single process.
Set a cap on listeners, bitrate and monthly transfer for each station, matched to the plan your customer bought.
Monthly usage per station, ready for billing and for spotting the stations that outgrow their plan.
Expose metrics in Prometheus format and watch them in the monitoring you already run.
CSV session and play logs plus aggregate tuning hours. Listener IPs are anonymised by default, which keeps GDPR work simpler.
A provisioning module for WHMCS, including import of bandwidth usage, so stations are set up and billed from the system you sell them in.
License keys are verified offline, with no call home. If a license lapses, streams never stop.

06Built in Crystal, made in Sweden
The lur is a bronze horn from the Nordic Bronze Age. About 3,000 years ago it was blown to send signals from one valley to the next. It is a long, curved tube that ends in a flat, decorated disc.
Lurcast is written in Crystal, a compiled language with Ruby-like syntax that produces a single fast native binary. It is built in Sweden, and was previously known as Crycast.
07FAQ
The core streaming server is open source under the GNU AGPL-3.0. You can run it, study it and change it for free. If you modify it and let people use your modified version over a network, the AGPL asks you to share your changes under the same license.
The Hosting edition is a commercial license on top of the core. It adds what radio hosting companies need to run many customer stations: the provisioning API, per-station limits, usage metering, Prometheus metrics, royalty reports and the WHMCS module.
Your streams keep playing. License keys are checked offline, and a lapsed license never takes stations off the air. Renew when you are ready.
Not entirely. Lurcast replaces the streaming server underneath a control panel: the part that takes the encoder connection and delivers audio to listeners.
Lurcast does not have AutoDJ or a customer-facing web control panel today, so a panel is still where your customers manage playlists and settings. Provisioning can run through the Lurcast API or the WHMCS module.
That is the goal. Lurcast accepts Icecast and SHOUTcast v1/v2 source connections, sends ICY metadata to listeners, and exposes Icecast- and SHOUTcast-compatible admin and stats endpoints. It is an independent implementation of those protocols, not a fork of either project.
No. Lurcast runs on your own servers, as a static binary, a Docker image or a systemd service.
